Figure 4-53 Appearance of the CE6857E-48T6CQ
The cooling system of the CloudEngine 6800 series switches uses front-to-back or back-to-front airflow depending on the airflow direction of the power modules and fan modules used.
Figure 4-57 Front-to-back airflow for port-side exhaust
Figure 4-58 Back-to-front airflow for port-side intake
The airflow direction of the power modules and fan modules required on the CloudEngine 6800 series switches depends on how the device is installed in a cabinet. Typically, cabinets in a data center have cold air flowing in from the front and hot air exhausted from the back. If a switch is installed with the power supply side facing the front and the port side facing the back, the switch needs to adopt fan modules and power modules with front-to-back airflow.
Power modules and fan modules using forced air cooling on a switch must have the same airflow direction. If a switch adopts power modules with back-to-front airflow, the switch must use fan modules with back-to-front airflow as well.

Console port | RJ45 |
Downlink Service interface | 48*10GE RJ45 (10GE interfaces are compatible with GE but do not support 100M/10M electrical interfaces. They only support full-duplex, not half-duplex.) |
Uplink Service interface | 6*100GE QSFP28 NOTE: 1. Each 100G QSFP28 port can be configured to work at 40 Gbit/s. 2. In V2R20C10, 40G/100G uplink ports cannot be split. In V2R21C00 and later versions, 40G/100G uplink ports 3 and 4 can be split into 4x25G and 4x10G ports, and the other 40G/100G uplink ports cannot be split. |
